BOOK-COVER PROTECTOR.

Application 'filed January 13, 1925. Serial No. 2,106.

To all whom it may concern:

Be it known that I, JARRETTE. THOMP- soN, a citizen of the United Statesof America, residing at Atlanta, county of Fulton, State of Georgia,haveinvented certain new and useful Improvements in Boole Cover Protectors;and I do hereby declare that the following is a full, clear, concise,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention relates to improvements inbook cover protectors and hasfor am object to provide a novel and practical, yet

simple form of book cover protector whose arrangement and constructionis such as will permit the same to be successfullyemployed as a coveringfor books of different sizes, being reinforced at the ends and cornersand affording a smooth and continuous or =unbroken exposed surface,thereby lending to the periodof practical usage of the same as well asgiving absolute protection to the book cover proper.

It is likewise an object ofthe invention to provide a book coverprotector having portions of the same, namely, at the corners andcenters of the upper and lower ends thereof, cut and forming tongues,which, in turn, are supplied with guide markings whereby tofacilitatethe fitting of the pro tector to a book cover, as well as theaccu rate folding of such cover protector and tongues during the processof fitting it'over a book cover.

Other objects of theinvention will-be in part obvious, and in partpointed out liere' inafter.

In order that the invention and its mode Figure 4 is an end view ofthatform of,

the cover shown in Figure 3;

Figure 5 1s a fragmentary detail in'plan showing the form .of book coverprotector shown'in Figure 3 in folded position;

Figure 6 is a vertical transverse section taken on the line 6-6 ofFigure 5;

Figure 7 is a plan view of another modified form of the book coverprotector; and

Figure 8 is a corresponding view of'the Having more particular referenceto the (ilIttWlIlgSfilIlCl especially in connection with that form ofthe invention disclosed in the Figures 1 and 2, the "book coverprotector may be stated to comprise a sheet of suitable material,generally indicated herein by-the numeral '1, suchas heavy paper,fabric, et cetera.' The sheet or body of the cover protector as shownherein is substantially rectangul-arin shape and has eachof the fourcorners thereof cut whereby to provide diagonally disposed tongues 2, 3,land 5, the edges of these tongues being preferably formed by straightlines of perforations or reverse side of that protector shown in Figure7.

accurately". identified and the same may, be

similarly folded when properly measured to a book cover, and in orderthat other cover protectors may be similarly folded, when covering booksexactly the same size, without needing -'to remeasure. The intermediatesideportio-ns of the sheet 1, that is, those portions directly betweenthe inner extremitiesof the tongues 2 and 3 and 4: and 5 are adhesivelycoated on the face opposite to that on which the lines are ruled, as isindicated by the numeral 9, the purpose of which will be subsequentlydescribed.

Other tongues '10 and 11 are provided upon'the top and bottom ends ofthesheet 1, centrally of the same, as is clearly shown in the Figure 1, andas will be noted, are

extended .or disposed transversely ofsaid sheet inopposed fashion. Thesetongues are formed with curved edges 12 and such edges may be completelysevered from the adjacent portions ofthe sheet 1 or 1f desired, curvedor curving lines of perforations or of scorings may be substituted inlieu thereof in order that certain portions of such tongues 10 and 11may be disjoined from the sheet 1, such as conditions or preference maydictate, this depending, as will be understood, uponthe size or depth ofthe book cover to be protected by the invention. Also, the basalportions of each of these tongues 10 and 11 are provided withtransversely disposed relatively spaced and parallel guide markings orlines generally indicated by the numeral 13, each of said guide lines ormarkings being appropriately designated by numerals 1%, or othersuitable nomenclature in order that they may be accurately marked andfolded during a fitting of the cover protector to a book cover, and ifproperly measured to other book covers the same size withoutremeasuring.

In the Figure 3, I have shown a slightly modified form of book coverprotector wherein the top and bottom tongues of the sheet 1 are formedin the following manner; curved portions or cut-outs, such as indicatedby the numeral 15 are formed in the top and bottom central portions ofthe sheet 1 and there is arranged transversely over the face oppositethe ruled lines of said sheet a strip of material 16 corresponding thefirst mentioned embodiment of the in-.

vention. By this peculiar arrangement or formation of the tongues whichare indicated at this time for the purpose of con venience by thenumerals 10 and 11, it will be understood that the cover will bematerially reenforced throughout its area of on gagement with the strip16. Therefore, since it has been found through actual ex periment that abook cover protector fre-.

quently gives way first in the center of books covered thereby, thisstrip 16, obviousy, will give double thickness'to the book coverprotector, thus lending materially to the strength and durability of thesame.

This strip 16 is only attached to sheet 1.

along its center enough to hold'it in place, retaining flexibility.

In using a book cover protector constructed in accordance with thoseseveral formsof the invention shown in the Figures 1 and 3, it will beunderstood that the sheet 1, chosen at this time, for purposes ofillustration, is laid upon a supporting surface with the markings uponthe various tongues uppermost. An openbook is placed in the center ofthe cover protector and is pressed open on the cover and heldsubstantially flat in such position whereupon suitable markings areinscribed upon the face portions of the sheet 1., that is, tongues 2 anda and 3 and 5, about one-fourth of an inch from the corners of the bookcover, allowing siuiicient to prevent folding corner tongues too shortto cover all corners of the book cover. Also, suit-able markings aremade upon the tongues 10 and 11 or 10 and 11' as the case may be, inorder that the length of the book may be accurately recorded upon thepro tector, allowance being made in these latter markings for a distanceof one one-sixteenth of an inch beyond the opposite ends of the bookcover in order that the protector will fully cover the same and willhave slight portions thereof extended beyond the book ends whereby tobest protect the same. lVith the sheet 1 marked in the manner prescribedupon the tongues 2, 3, at and 5 and lO'and 11 or 10 and 11', the book isthen removed and the tongues 2 and 4 and 3 and 5 are folded inwardlyupon themselves along those particular guide markings or lines 7adjacent the markings indicating the corners of the book cover. Thetongues 10 and 11 or 10 and 11 are now folded transversely of themselvesalong the particular guide markings or lines 13 or 13 thereon, the samebeing turned inwardly of the cover protector, as are the diagonallydisposed tongues 2 and 4E and 8 and 5. With the six tongues 2. t, 3 and5, 10 and 11 or 10 and 11 folded inwardly of the sheet 1, the top andbottom portions of the opposite ends and adjacent portions of said sheet1, that is, those portions as between the various corner tongues and thetongues 10 and 11 or 10 and 11' are folded inwardly upon a straight lineand over the book cover so as to align approximately flush but slightlybeyond the adjacent marginal portions or edges of the book cov r, firstrefolding corner tongues if necessary. At this time, the intermediateportions of the opposite sides of the book cover protector, that thoseportions having the adhesively coated extremities 9 are folded uponthemselves along a straight line over the outer marg ly folded parts ofthe sheet 1., that is, those parts that lie between the diagonallydisposed tongues and the tongues 10 and 11 or 10 and 11. The adhesivelycoated extremities 9 are pressed downwardly for a length of time toensure adhesion between the contacting. portions. In a similar manner,the opposite side of the sheet constituting the llO book cover protectoris folded over the opposite side of the book cover, that is, the top andbottom portions between the corner tongues 2 and 4E and the end tongues10 and 11 or 10. and 11' are folded inwardly upon a straight line andover the book cover and finally, with folding of the intermediateportions of the sheet upon themselves in the manner hereinbeforedescribed, the adhesively coated extremities 9 of the intermediate sideportions are then moistened and pressed into permanent engagement withadjacent portions of the folded intermediate top and bottom portions ofthe sheet 1.

In the Figure 7, have shown yet another modified form of my improvedbook cover protector, wherein one side, the left side as shown herein,of the cover protector is partially folded and sealed. The upper or topof this particular side of the book cover protector is left open andwith proper marking of the graduated top tongue 1"? which is then foldedinwardly and transversely upon itself in the manner hereinbeforedescribed, said left side of the folded cover protector sheet, indicatedfor the purpose of convenience by the reference numeral 1 is then foldedalong a straight line and over the adjacent upper end of the book coverreceived therein, whereupon an adhesively coated extremity 18 of theintermediate side piece 19 is moistened and pressed into permanentcontact with the adj acent part of such folded portion.

The opposite or remaining and right side of this sheet 1 is formed withdiagonally disposed tongues 3 and 5' havin ruled transversely thereof aplurality of relatively spaced parallel guide lines or markings 7 whichin turn are adapted to be indicated by numerals or other suitablenomenclature 8 diagonal corner tongues 3' and 5' is such as to providean intermediate piece 20, whose opposite extremities are coated on oneface with an adhesive 21.

Thus, it will be understood that with engagement of the left side of thebook cover in the left and partly folded side of the sheet 1 theopposite side of this cover is adapted to be covered by the protector byfirst marking the guide lines or markings 7 upon the tongues 8 and 5',then folding such tongues along the indicated guide markings inwardlyand transversely of thenr selves, whereupon the intermediate top andbottom portions of the right side of the sheet 1 are folded uponthemselves on a straight lineaover the top and bottom of the book coverso as to be arranged adjacent but slightly beyond the adjacent marginalportions of the book cover side. At this time, the intermediate portion20 is folded inwardly upon itself along a straight line over the outerportion of the book cover side The forming or arrangement of theseandthe coated extremities 21 are moistened and the same then pressed intopermanent engagement with adjacent portions of the inwardly.folded topand bottom end portions. Thus, a complete bool: cover protector isafforded.

From the foregoing, it will be understood that I have provided a simple,but highly efficient form of book cover protector, the construction orformation of the same being such as to provide a one piece re-enforcedadj ustable book cover protector which may be made of various ordifferent grades of paper or other suitable flexible material; (116 sizeof which protector may be properly and quickly fitted to books ofdifferent or varying dimensions, since no cutting is required, andfolding of the cover protector is rendered simple and accurate by meansof guide lines or markings hereinbefore described.

The corners of this book cover protector are so designed that thefolding in thereof, according to directions, gives double thick ness andextra protection for several inches at each corner of a book so coveredand protected without sacrificing, in the least, strength or durabilityof the cover; the surface or exposed face of the cover protector beingperfectly smooth and hence, providing an important and advantageousfeature in this respect, since an uneven surface has been foundextremely objectionable due to the liability of the engagement ofvarious objects therein with the tearing or premature wearing of theprotector.

The tongues 2, 3, 4:, 5, 10, 10', 11, 11', 3 and 5 occurring at the topand bottom of the various sheets and in the centers thereof providere-enforcement and if properly folded, protect the book at those pointsmost needed. Certain of these tongues are curved in a way to lendmaterially to the strength and durability of the same and in thisconnection, it should be mentioned that if desired, the tongues may beformed in their respective sheets of the protector by being cut forcertain distances and then perforated or scored for short distancesinwardly, thus permitting their severance from the body portions oftheir respective sheets only as necessary or as is required.

Manifestly, the various constructions shown are capable of considerablemodification, and such modification as is within the scope of my claims,I consider within the spirit of my invention.

I claim 2- 1. A book cover protector comprising a sheet of materialhaving diagonally disposed tongues formed in the corner portions thereof and adjacent the opposite ends of the same, the extremities of thosefree portions of the opposite sides between said tongues beingadhesively coated upon certain of their faces, and opposed transverselyextending tongues arranged adjacent the center portions of the top andbottom of the sheet.

2. A book cover protector comprising a sheet of material havingdiagonally disposed tongues having outwardly diverging edges formed inthe various corner portions thereof, the top and bottom portions of saidsheet being cut away adjacent the central portions thereof, a stripjoined to one face of said sheet along its center disposed transverselyof the same and having its opposite extremities overlying said cut awaycentral portions of the top and bottom portions of the sheet, theextremities of those free portions of the opposite sides of the sheetbetween the diagonal converging tongues being adhesively coated uponcertain of their faces, and transversely arranged relatively .spacedparallel guide markings inscribed upon portions of each of said diagonaltongues and those por tions of the strip overlying said cut away top andbottom central portions.

3. A book cover protector comprising a sheet of material having diagonaltongues formed in the same adjacent its various corners, each of saidtongues being provided with relatively spaced transversely extendingparallel guide markings, the extremities of those free portions of theopposite sides of the sheet between the diagonal tongues beingadhesively coated upon certain of their faces, one side of said sheetbeing folded and having the bottom portion thereof permanently joined bythe adjacent adhesively coated extremity and the upper portion of suchfolded sheet being open, and opposed transversely extending tonguesarranged adjacent the center portion of the top and bottom of saidsheet, portions of said transversely extending tongues being providedwith relatively spaced transversely extending parallel guide markings,as and for the purpose set forth.

In witness whereof I have hereunto set my hand.

JARRETT E. THOMPSON.
